Here is what we have planned for Collaborate 12!

Keeping up with such rapid-fire changes is a project in itself. In the database triangle of Oracle, SQL Server, and MySQL, patches, updates, features, tricks, and tips are booming, and so is this Log Buffer Edition.

Oracle VM: What If You Have Only 1 HDD System?

In my previous post, I described how to install Oracle VM and Oracle VM Manager on the same sandbox. However, to start playing with Oracle VM v3 you need to configure some storage to be used for new VM hosts. The problem is that Oracle states that you should allocate a full HDD for VM host storage. If you have just one HDD in your system, then you are in trouble since part of it is already occupied by the Dom0 host.

Using Oracle VM with Amazon EC2

If you’re planning on running Oracle VM with Amazon EC2, there are some important limitations you should know about. As part of my work getting the Oracle Linux Unbreakable Enterprise Kernel 2 working, I tried using the Oracle-supplied Oracle Linux 6 AMI images that are listed as community AMIs by Amazon.

Testing Out Oracle’s Unbreakable Enterprise Kernel 2

I’m going to test Oracle’s Unbreakable Enterprise Kernel out, and an obvious way to do this would be using Amazon EC2, providing high-capacity instances on demand.

Disabling Oracle triggers on a per-session basis

The method of disabling triggers requires Oracle 11.2.0.2+ or 10.2.0.5+, plus execute permissions on sys.dbms_xstream_gg. Since it’s a call to an XStream package, it may also require a XStream license. So if I haven’t scared you away yet, here’s a quick testcase:

Oracle Database Appliance — Storage expansion with NFS (dNFS, HCC)

The biggest objection to Oracle Database Appliance (ODA) we hear from customers is about 4TB usable space limit (tripple mirrored 12TB of raw storage). I think most of the times this is more a perceived barrier rather than objective — more along the lines of being afraid to hit the limit if the system grows a lot. Nevertheless, Oracle has been always listening customers’ concerns when it comes to purchasing barriers. Of course, this time is no exception.
